Migrating involves copying the configuration from a previous release of a WebSphere Application Server product into a new release. Coexisting involves running a new release of a WebSphere Application Server product on the same machine at the same time as you run an earlier release or running two installations of the same release of a WebSphere Application Server product on the same machine at the same time.
For a compilation of links to documents and resources to help you plan and perform your migration, visit Knowledge Collection: Migration planning for WebSphere Application Server.
If you have a previous version, you must decide
whether to copy the configuration and applications of the previous version
to the new version. Migration does not uninstall the previous version. To
run an earlier release and the new release at the same time is coexistence.
To support coexistence, you need to provide non-default port assignments during
profile creation. See Overview of migration and coexistence for
more information on coexistence.
You can also find more
information on migrating to Version 6.0.x in the following document: WebSphere Application Server
Version 6 Migration Guide.
If you have a previous
version, you must plan whether to migrate the configuration and applications
of the previous version to the new version. Migration does not uninstall the
previous version. The earlier release is still functional. If you run the
earlier release at the same time as the WebSphere Application Server for z/OS
Version 6.0.x installation, the two versions are coexisting. The migration
articles describe migration from WebSphere Application Server for z/OS Version
5.x to WebSphere Application Server for z/OS Version 6.0.x.
You
can also find more information on migrating to Version 6.0.x in the following
document: Migrating
from WebSphere for z/OS Version 5.x to Version 6 - An Example Migration.
You can coexist with or migrate the applications and configuration from a previous version of WebSphere Application Server.
Migration from Version 5.x to Version 6.0.x does
not require extensive tuning. See Migrating product configurations for a description of fine tuning a migration. Part of
the procedure for using the migration tools includes a description of what
to tune after using the tools.

You can coexist with or migrate
from a previous version of WebSphere Application Server for z/OS.
